Fig. 1 is a tree seedling root sampling tool according to the present invention.
Wherein, 1-sampling tube, 2-solid cylinder, 3-cross bar, 4-round hole, 5-nut, 6-sharp part.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in figure 1, a sapling root sampling instrument, including sampling tube 1, cover in the solid cylinder 2 at sampling tube top, and run through the horizontal pole 3 of solid cylinder and sampling tube, the sampling tube bottom has continuous bellied sharp-pointed part 6 along the circumferencial direction, solid cylinder top and sampling tube top parallel and level, horizontal pole outside both ends respectively have a round hole 4 for connect the stay cord.
In this embodiment, the horizontal pole surface has the external screw thread, and threaded connection has a nut 5 of a pair of spacing horizontal pole on the horizontal pole, thereby supports the surface of top sampling tube through the nut during installation and lock the horizontal pole 3 that runs through solid cylinder and sampling tube.
In order to enable the sampling tube 1 to smoothly enter the soil and avoid soil pollution in the embodiment, the sampling tube 1 is made of a non-metal hard material, a sharp part adopts continuous angular protrusions as shown in fig. 1 so as to be beneficial to reducing resistance to cutting the soil, the inner diameter of the sampling tube is 15-25cm, the length of the sampling tube is 75cm, and the inner diameter of the sampling tube 1 in actual design can be adjusted according to the age of a seedling to be taken.
The solid cylinder 2 is sleeved on the upper part of the sampling tube, so that the upper part of the sampling tube 1 is of a solid structure, and the purpose is to knock the upper part of the sampling tube to penetrate into the soil layer. The solid cylinder 2 has an outer diameter slightly smaller than the inner diameter of the sampling tube 1 so as to be capable of being just inserted into the sampling tube 1, and has a length of 20 cm.
The hand is prevented from being hurt when the operation is applied with force, and the outer layer is provided with a soft sleeve.
The method and the process of the invention in practical use are as follows:
the specific operation steps are as follows:
